- I BY W AUOHEYS I teched, these stems operating in steni guides 44, projecting oppositely from the cylinders, and at their outer ends the valves are provided with projecting knobs 45.

46 indicate springs which keepthe valves yieldingly seated. v

The projecting knobs 45 are intended to be en aged by teppet-rollers 47, carried on stud b0 ts 48, progecting from rin s 49. These rin s are mounted loosely on t e bearings 17 an are rovided, as shown best in Figs. 2 to 5, with s ots 50, in which fit ins 51, projecting from the bearings 17. T is arrangement mounts the tappets on the beerings end at lows them a limlted independent movement;

As the cylinders and valves rotate the knobs 45 ere successively engaged with the teppete, and in this manner the valves are opened. As soon as the valves disengage the te'ppets the valves close under the notion of the springs 45. The limited independent move mont allowed the teppets is for thepurpose of establishing the proper relative position. of the ports upon reversing the direction of rotetion of the en ine.

Figs. 2 and 3 indicate the ports in the post tion they will assume when, for example, the engine is running ahead, and upon the reverse! of the engine the valves and their knobs 15 will move backward, carrying the teppote 47 with them for a distance equal to the length of the slots 50 in the rings 49, whereupon the ends of the wells-of the slot 50 rengege te pins 51, and the velveteppets become 5 tionnry and active This lost motion. allows the parts upon reversal to assume the proper relative position before the renewed opera tion ol" the valves takes place.

52 indicates ignitcrs which are provided to ignite the piston charges introduced into the cylinders 30, These igniters are preferably of the jump-spark type. One'termi'nel of the secondry current is suitably ground on the engine, and the other terminal is led by suitable conductors to insulated contact-shoes 53, supported by any desired meens-for e20 ample, those described in my copending application above referred to on. the cammed members 11.

- the foui cycle notion.

Various changes in the form, proportions, and minor details of my invention may be resorted to at will without do "ing from the spirit and scope thereof. co 1 con sider myseii" entitled to oil .rE-ilfil a tions es may lie within the terms of my cl Having thus described the r rer In other resnects. however to the eyl-t IOO eaasss of my invention, What 1 claim as new, and

desire to secure by Letters Patent, is

1. In an engine, the combination of a base, av stationary canuned member carried thereby, an outWardly-projecting wall carried by the canuned member, a bearing, an arm connecting the beering with the said Well, a shaft revolubly mounted in the bearing, a cylinder carried by and turning with the shaft, a piston operating in the cylinder, a part engaging the cammed member and con nected to the piston, and a fan-blade at each side of the cylinder, attached to said shaft and turning therewith.

In an en ine, the com bination of a bed, two stationrir undulating circular cams sustained thereby and arranged opposite to each othin, revoluble shaft disposed contrally of the cams, means for mounting said shaft, :1 cylinder attached to the shaft, extension-wills arrai d to turn with the shaft and cyi der and raving guides therein, a piston operating in the cylinder, and a part in connccl iui with the pis on, aid part running in the engaging t n (innsv 3. In an engine, the combination of a base, a stationary inidulating circular cam sustained thereby, a bearing of said oznn, shaft revolubly carried in the bearing, a fan-blade attached to the shaft, means for sustaining the bearing from the earn, a cylinder attached to and turning with the shaft, e piston operating in the cylinder, and a part having connection with the pisston and engaging specified ides of the Maori-walls end disposed centrally I the cam, for the purpose I l LOR -k E. DEW.

4, In an engine, the combination of a base, a stationaryundulating circular cam attached thereby, a bearing disposed centrally of the cam, a shaft revolubly carried in the bearing, arms in the form of fan-blades connecting said bearing With said cam and sustainin the bearing, additional fan-blades attache to the shaft adjacent to the first-named blades, a cylinder attached to and turning with the shaft, :1 piston operating in the cyli1 ler, and a part having connection with the piston-and engaging the cam.

5. In an engine, the combination of a bed, two stationary undulatoiy circular cams sustained thereby and arranged opposite to each other, e revoluble shaft disposed centrally of the cams, outwardly extending walls carried by the cams, bearings in which the shaft mount-ed, means extending between the bearings and said outwardly-extending Walls to support the bearings, a cyl inder attached to the shaft, valve devices for i the cylinder, said valve devices being inclosed l by said outwardly-extending Walls, a piston 7 operating in the cylinder, a rodin connection [with the piston, uides having connection I with the cylinder and shaft, and a cross-bar in connection With the piston-rod and runl l l l ning in the guides, said cross-bar having its ends engaged in said cams.

In testimony whereof I have signed my name to this specification in the presence of I two subscribing Witnesses.
